请教OG 11 VERBAL-44
44．Laws requiring the use of headlights during daylight hours can prevent automobile collisions. However, since daylight visibility is worse in countries farther from the equator, any such laws would obviously be more effective in preventing collisions in those countries．In fact，the only countries that actually have such laws are farther from the equator than is the continental United States.
Which of the following conclusions could be most properly drawn from the information given above?
(A) Drivers in the continental United States who used their headlights during the day would be just as likely to become involved in a collision as would drivers who did not use their headlights．
(B) In many countries that are farther from the equator than is the continental United States poor daylight visibility is the single most important factor in automobile collisions-
(C) The proportion of automobile collisions that occur in the daytime is greater in the continental United States than in the countries that have daytime headlight laws．
(D) Fewer automobile collisions probably occur each year in countries that have daytime headlight laws than occur within the continental United States．
(E) Daytime headlight laws would probably do less to prevent automobile collisions in the continental United States than they do in the countries that have the laws．
Argument Construction
Situation Laws requiring the use of headlights during the daytime are more effective at preventing car collisions in countries with 10wer daylight visibility, that is，in countries at greater distances from the equator．The only countries having these laws are those located farther from the equator than is the continental U．S．
Reasoning What conclusion can be drawn from this information? Countries with daytime headlight laws are all farther from the equator than is the continental US．The location is significant because daytime visibility is worse in those countries than it is in the continental U．S．How effective at preventing collisions would such laws be in the continental United States with its greater proximity to the equator? It is reasonable to conclude that such laws would be less effective at preventing collisions there than they are in the countries farther from the equator．
A This contradicts the given information that daytime headlight laws can prevent automobile collisions Although daytime headlight use may be less effective in countries with more daylight，it cannot be concluded that U．S．drivers using daytime headlights would gain no benefit from them and would have collisions the same as those who do not．
B The passage offers no evidence for the conclusion that poor visibility．is the greatest cause for collisions in these countries．
C Data are required to make judgments about the proportion of daytime collisions·
D Without specific data．no conclusion can be drawn about the relative number of accidents that occur．
E Correct．This statement properly identifies a conclusion to be drawn from the given information.
The correct answer is E．
1.看完OG的解释，思路还是不清晰，麻烦大家帮忙看下，正确选项是怎样推出来的！
2. How effective at preventing collisions would such laws be in the continental United States with its greater proximity to the equator?
应该怎样理解？
总觉得本题强调的不是距离的问题，而是有效性的问题，大家怎么看呢？
谢谢！
